MySQL pip3 安裝錯誤：元數據生成失敗

Question

我嘗試更新 pip 並安裝不同的軟件包，但似乎沒有任何效果。 我不確定我是否必須在 konsole 或 alacritty 中運行命令，但我們將不勝感激。 我用fedora順便說一句

 sh-5.1$ pip3 install mysql
 Defaulting to user installation because normal site-packages is not writeable

  note: This error originates from a subprocess, and is likely not a problem with pip.

在安裝之前，您必須解決依賴關系。

sudo apt-get install python3-dev libmysqlclient-dev

然后在虛擬環境中：

pip3 install mysqlclient

然后

  pip3 install mysql

它應該工作
